Sungura Study

Efficacy, safety and tolerability of switching to DTG/3TC single tablet regimen from B/F/TAF in older persons living with HIV in Kenya.

Duration

96 weeks

Participants

197 adults

Age criteria

≥ 60 years

Study Design

Phase 3b, multi-center, open-label, single arm clinical trial over 96 weeks to assess the efficacy and safety of switching to dolutegravir and lamivudine (DTG/3TC) single tablet regimen from bictegravir, emtricitabine and tenofovir alafenamide (B/F/TAF) in 197 adults aged 60 years and older living with HIV in Kenya.

Primary Endpoint

Study Objectives

Assess the efficacy of switching from B/F/TAF to DTG/3TC in maintaining viral suppression

Evaluate the safety and tolerability of DTG/3TC in older adults living with HIV

Monitor changes in renal and bone biomarkers following the switch

Assess patient-reported outcomes and quality of life measures

Evaluate treatment satisfaction and adherence to the new regimen
